[2. Dry-Battery Housing]

Next, there will be described on the dry-battery housing directed to thepresent embodiment wherein an electrode terminal member 101 of thedry-battery housing is replaceable, by referring to FIG. 1 through FIG.11. FIG. 1 through FIG. 5 show detailed configuration of the dry-batteryhousing from which electrode terminal members 101 are removed. FIG. 6through FIG. 11 show detailed configuration of the dry-battery housingin which the electrode terminal members 101 are placed. Except for thematter of presence or absence of the electrode terminal members 101,views depicted in FIGS. 6, 7, 8, 9 and 10 respectively correspond toviews in FIGS. 1, 2, 3, 4 and 5.

As shown in FIG. 1 through FIG. 11, the dry-battery housing directed tothe present embodiment is arranged in a dry-battery housing unit 10installed in a body 1 of a label printer.

The dry-battery housing unit 10 is substantially made of a rectangularparallelepiped hollow portion 11 defined by an opening portion 12, sidewall portion 13, a side wall portion 61 and a bottom portion 14. Forarrangement of an electrode terminal member 101 to the dry-batteryhousing unit 10, the electrode terminal member 101 is arranged so as toface the side wall portion 13 (refer to FIG. 6 through FIG. 11). In thepresent embodiment, three electrode terminal members 101, each beingarranged so as to face the side wall portions 13, are placed in parallelto one another and in perpendicular to the bottom portion 14 of the drybattery housing unit 10.

Flange portions 21 are arranged at both sides (namely, at first side andsecond side) of each electrode terminal member 101 arranged so as toface the side wall portion 13. Each flange portion 21 is arranged so asto project from a border 12A toward the side wall portion 61 thatopposes to the side wall portion 13.

A first partition plate 31 is arranged at an outside with respect tofirst side of each electrode terminal member 101 arranged so as to facethe side wall portion 13 of the dry-battery housing unit 10. Each firstpartition plate 31 is arranged on the side wall portion 13 so as toproject toward inner of the hollow portion 11 of the dry-battery housingunit 10. Each first partition plate 31 serves to divide dry batteries 51(refer to FIG. 9 and FIG. 10) housed in the dry-battery housing unit 10.

Eachpartition plate with indication of the two kinds of numerical references31 and 32 is a double functional plate serving as first partition plate31 and second partition plate 32 simultaneously. It is understandablefrom FIG. 8 that the second partition plate 32 depicted in FIG. 9 shouldserve as first partition plate 31 simultaneously. However, numericalreference 31 is not indicated in FIG. 9 in view of positional relationcorrectness; the double functional partition plate of FIG. 9 is seenfrom the side indicated with the arrow B in FIG. 8. More specifically,since the seeable side of the double functional partition plate in FIG.9 should face second side of the electrode terminal member 101, onlynumerical reference 32 should be indicated in FIG. 9. It is alsounderstandable from FIG. 8 that the first partition plate 31 depicted inFIG. 10 should serve as second partition plate 32 simultaneously.However, numerical reference 32 is not indicated in FIG. 10 in view ofpositional relation correctness; the double functional partition plateof FIG. 10 is seen from the side indicated with the arrow C in FIG. 8.More specifically, since the seeable side of the double functionalpartition plate in FIG. 10 should face first side of the electrodeterminal member 101, only numerical reference 31 should indicated inFIG. 10. The similar numerical indication manners are applicable to FIG.3, FIG. 4 and FIG. 5.

Each first partition plate 31 includes a first fixing plate 41 thatprojects toward a second partition plate 32 from the first partitionplate 31 is independent of a flange portion 21. Further, the firstfixing plate 41 is arranged on the first partition plate 31 so as toface a first-side rim portion 114 (refer to FIG. 12) of an electrodeterminal member 101 that is arranged so as to face the side wall portion13 of the dry-battery housing unit 10. Thereby, the first fixing plate41 serves to fix the electrode terminal member 101 arranged so as toface the side wall portion 13 of the dry-battery housing unit 10.

Each second partition plate 32 includes a second fixing plate 42 thatprojects toward a first partition plate 31 from the second partitionplate 32 is independent of a first fixing plate 41. Further, the secondfixing plate 42 is arranged on the second partition plate 32 so as toface a second-side rim portion 121 (refer to FIG. 12) of an electrodeterminal member 101 that is arranged so as to face the side wall portion13 of the dry-battery housing unit 10. Thereby, the second fixing plate42 serves to fix the electrode terminal member 101 arranged so as toface the side wall portion 13 of the dry-battery housing unit 10.

It is to be noted that a first fixing plate 41 and a second fixing plate42 are present in the same plane.

Between a first fixing plate 41 and a second fixing plate 42, there is aspatial area of which width W (refer to FIG. 3) is made wider at a sideheading for the opening portion 12, in other words, an upper side of thespatial area, namely, above the reference symbol W in FIG. 3. Morespecifically, the width W of the special area is made wider above thereference symbol W in FIG. 3 that is a portion to allow a negativeterminal portion 103 of an electrode terminal member 101 to project intothe hollow portion 11 of the dry-battery housing unit 10 from the planeof the first fixing plate 41 and the second fixing plate 42 when theelectrode terminal member 101 is arranged so as to face a side wallportion 13 of the dry-battery housing unit 10.
